.To all whom. it may eorecrm Bo it known that I, CHARLES A. Mizuno-ss,

a citizen of the United .5mt-; and o rif-,aident of Yonkers, in the countyo if-eschesar and 5 Stato of New York, havo invonbzd new and uul Improvements in Paleis-diie Alloys. of

which the following is a full, clam-4 and exact description.

Tho invention roiot to metals Boch a8 mo lo nsod'in casting-nmoiinos of any coostu@ "tion for forming ordinary typo-s1, stozooypos,

monotypes, slugs, Babbitt bearings amd other bearings, solder-3, :mdolhor arioleo in which o uniform or even distribution of tho con stitooot metals of the aiioy is desirable and essontxol.

The object of the invent-ion is to provide cari-:zin now and useful improvements in the mniaotura of metallic :alloys whorooy a zo more oven and uniform blending of ho consituen metals is ofon' od, the producI boing in the form of mgmooa or small patioioa which gn bo oon'oniently honiiiod, .shippod, :md finally feci into melting-pot to be ro- :5 duced to. o molon omis therein, the molten metal when imo the desired oi'icio producing an amciopoosesimg a high quality, as the constituent momia am inmmoly blended in tile deairod popor'tiona.

The i-esult of such iniuoncos is .that Img@ solid mossos or' the alloy are bot uniform in composition. The heaviest component may bo in the bottom of tho bar or pig,ort,he components may havosag 55 regata-l themselves ifi-irregular mimosa on occozmt of their selective solidication. or gmx. ity o'r' contriugnl fos'co moy have caused suchmixing-pot that the rst pig cost, thomotal of which it is comimsod 6 having been taken necsai-ily from the trop or bottom orsome oiier particu-lax' port of tr'oo molon ms, is not the somo as to tho-propotions of its consituent as o bm oomposed of mom! token from A:mchox peut This makes a moi; iiioronoo in the composition of hors or ofthe first mn of metal as compared with oiiers com. lo'or.

The apparatus iilustmod in Figs. 1 and 2s providorl Wit-n a-iorge oo or melting-pot 106 action the fragments B lstruction to produce e. molten alloy, 'hich A, in which the constituent metals furthe :illuy B :ire plut-ed in nlmutthcdesircd proportions, s the metz-ils being heated by suitable burners() f :ind intimntely mixed or blended with euch otherbysuitnblestir'rersorwitntorsDJnOunted to rcvolvein the pot A unddriven bym suitable overhead driving device D. The blended metals forming the allow B nre discharged through n spout E t'rou the pot A. the outflow of the molten metal lwingeontrolled by a vulve I", nrrnnged in the spout und connected with n lever F' under the control of the operator. The molten alloy flows from the spout E into n distributing;r box or trough G, provided in its bottom with n rou of opertures discharging; the moltennetnl in sepurnte Streams onto the upfer run of nuendless belt il, driven by n. suitable mechanism ir n forward direction-that is, in the lirection of the arrow 'so that the molten alloy hnrdens into bars, finally passing over s tnbley il',to be cut into small fragments B by the use of n suitnble cuttingdevice I, pretierubly in the form of n driven rotary cutter, as indicated in the drawings.

The fregments' drop over n. chute J into a tumbling or clenning barrel K, preferably set'in :in inclined position und provided with u. screen-rim and spiral retainers inside of the rim, so that when the barrel is rotl'ited the' frscfments B are caused to rub against erich othersnd ngainstthe rim while beingr fcddownwurd ut. the same time in the barrel K, owing to the action of the spirnl retainers. By this are freed of .scnlesor other external extrnneous matter, so that the fragments in n cleaned and somewhat-polished. state falltinnllyontonbeltI,wl1iletlic removed scales or other extraneous metter passes the through meshes ol"- thebarrel-Screen onto a chute N to be discharged into a receptacle O.

The cleaned fragments B ere carried by the belt L in a forward direction to he inallyds charged from the belt over a. chute P into mixer Q, preferably in the form of a barrel adapted to be rotated, s'o as to mix the frugmen'ts Bs while in bulk to insure n thorough intermingling ofthe several fragments. These fragments can-` be readily packed and conveniently shipped to be tin'ally subjected to heat in a melting-pot. R of any approved conwhen cast into ordinary types, stereotypes, monotypes, slugs, Babbitt bearings, solders, and like` articles produces such'articles in which a uniform eve-n distribution of the constituent metals of the, alloy is had'.

In pouring the molten alloy from the pot R, as required, it isevident that. for a. continu 'ous operation solid metal in some form must liei'ed lvrimliifzi-lly iutn the potN and by having thi` metil in mgment form it is evident that the molten metal already in the pot vis not linble to be chilled to :in undesirable degree :ind nt the seme time n quick renielti'nig of the metal fragments tnltes pince in the pot it, so

molten metal inthe Said not is nlwnys in n propercondi'tion for being enst into the desired nrtiele. v

As heretofore practiced large metal-:alloy blocks or bers S, ns shown in Fig. 6, were employed; but it is evident that such largo hlocksor huis have i; tendency to chill the metnl :already in the pot und `owing to their size requires large amount of heat. before passing into the molten state.

.ln the moditied form (shown in Fig. 1)11 number of furnnees or pots A7, A', und Anre employed, each containing: n. constituentv metal for the alloy-t-lmt is, one may contain lend, another :intim-(my, und n third silveraind the several spouts E', E, and E3, lending from the pots, for conductini,r the molten metals to the distributing-box nre so arranged ns to `run the several constituent molten metals to @other und mix the sinne previous to passing the metals' into thedistributing-box G The blended motels in n molten state are run from the llistribut-ing-b0x G onto the belt lI to be formed into solid burr., which nro then chopped or cut up into fragments und further trmited, as above described with reference to Fig. l.

In either of the two enses mentioned the constituent motnls nre well blended while in n. molten state, und the resultant fragments nre nguin mixed in bulk, sotl-int the intermingled fragments of e. molten metalis produced which allows of formingr types und other articles of a very 10 high quality. l

Having thus described my invention, I claim as new and desire to secure by Letters Patent- `bA body of alloy' for chargingmelting-pots,

to-be cast into bearings, printers types or the 105- like, conmining rwnsituents susceptible to separativc influences when the alloyis in a molten state, said bodyv or charge consisting of a. mass of the alloy converted into small solid pieces orbits thoroughly comminged, the con- I I0 stituent metals of the alloy being distributed throughout the. mass or charge in the proper proportions, as set forth.

In testimony whereof I have signed my name to .this specification scribing witnesses..
